Title: Pump rotor set with increased fill limit
Inventor: HODGE STEPHEN MARK
IPC: F04C2/08
Filed: 2002-10-22
Abstract: The rotor 10 or annulus (stator) 60 of a pump has a number of teeth 14, 64 and a number of blind filling slots 18, 66 between the teeth and extending from an end face of the rotor 10 or annulus 60. Two annulus with filling slots 66 in their end faces may be fitted back-to-back (figs. 5,6) so that peripheral filling windows (102, 122) are formed. The filling slots are provided in order to increase the "single end filling limit", ie the amount of fluid that a particular rotor/annulus set can admit through one end without cavitation/flow truncation occurring, and may also increase the "double end fill limit", ie the amount of fluid that can be admitted into a rotor set from both ends.

Title: A combined elastomeric and metal sealing system
Inventor: MILBERGER LIONEL J
IPC: E21B33/04
Filed: 2002-10-29
Abstract: A sealing system for sealing a wellhead (50, figure 2) comprises an axially extending annular packer element 10, a wedge ring (60, figure 2) configured to expand the packer element 10, and a positioner 40 for moving the packer element 10 axially downward with respect to the stationary wedge ring (60, figure 2) to allow the wedge ring (60, figure 2) to radially expand packer element 10 for engaging the wellhead (50). The packer element 10 comprises a metal base 12, a first elastomeric seal body 20, and a second seal body having an elasticity lower than the first seal body 20. The second seal body 22 may be formed from a soft metallic material. The seal bodies 20, 22 are held in position with ribs 14, 16, 18 extending from the metal base 12. Upon movement of the positioner 40, the first seal body 20 engages the wellhead (50, figure 2) to make an initial seal, and then hydraulic forces due the sealing engagement moves the packer element 10 to an expanded diameter so that the second seal 22 engages with the wellhead (50, figure 2) to provide a second seal. The packer element 10 comprises axially spaced protrusions 26, 28, 30, 32, 34, 36 protruding from the metal base 12 to provide a redundant metal-to-metal sealing engagement with the wedge ring (60, figure 2).

Title: Apparatus for stirring molten metal comprising electromagnetic induction
Inventor: HOUGHTON BARRY
IPC: F27D27/00
Filed: 2003-03-28
Abstract: Flow inducement or stirring apparatus 500 is able to circulate molten metal in a vertical plane. Preferably the apparatus 500 includes electromagnetic induction means. In use, the apparatus 500 may be inclined to the horizontal, at an angle of 45 or 30 degrees to 60 degrees, and may be positioned on an inclined furnace wall 502. Alternatively, the apparatus 500 can be positioned at an angle on a vertical wall by an attachment cradle or port 503. This cradle 503 may have an aperture which allows additives to be introduced to the molten metal, or sampling and degassing. Vertical circulation of the melt allows scrap materials etc. to be dragged down and submerged in the melt. The speed of stirring may be variable and may be pre-settable up to 50 Hz. The stirring apparatus 500 may be bi-directional, so that flow can be reversed to extract melt from a furnace. The electromagnetic induction may act through a thin, perhaps metal carbide, plate which may comprise tiles. Additionally, horizontal flow may occur between two chambers, wherein metal is melted in a first chamber. Also, an area for loading heavy scrap may be provided, and flow may be directed so that the heavy scrap is not submerged.

Patent GB-2398973-A (GB)
Title: Paging in provision of MBMS
Inventor: KUWANO HIROAKI
IPC: H04B7/26
Filed: 2004-01-08
Abstract: The present invention preferably uses a TMGI (Temporary Mobile Group Identify), which is an identifier peculiar to an MBMS service, instead of an IMSI, which is an identifier peculiar to a UE, to prepare a paging message on the basis of this TMGI and determine a Paging Occasion (transmission frame timing of a PICH) and a PI bitmap. Consequently, since it becomes possible to send the paging message with a group of UEs subscribing to an identical MBMS service as a unit, congestion of radio channels due to the transmission of the paging message is eliminated. In particular, UEs using other services are not affected by congestion.

Title: A dental floss device
Inventor: DOUGAN MICHAEL
IPC: A61C15/04
Filed: 2002-11-22
Abstract: A dental floss device (1) comprises a handle (2) having a head piece (3) and a disposable holder (4) for a length of dental floss (5). The holder (4) comprises a base portion (20) and a pair of spaced-apart jaws (21) extending from the base and which extend to embrace the head piece (3) of the handle (2) when the holder (4) is in a correct alignment configuration with respect to the handle (2). The device has an interlock which ensures that the holder (4) can be interengaged with the head piece (3) only when the holder (4) is correctly aligned with the head piece (3). The interlock comprises a head interlock part provided by interlock grooves (10) and a holder interlock part provided by corresponding interlock tongues (11). There are two interlock grooves (10) and corresponding interlock tongues (11) which slidably interengage when the holder (4) is correctly aligned with the head piece (3). If the holder (4) is turned so that it is not correctly aligned with the head piece (3), the interlock tongues (11) of the holder(4) prevent engagement of the holder (4) with the head piece (3). Thus there is no risk that a user will incorrectly align and engage the dental floss holder with the head piece (3).

Title: Method of multiplexing ionization signals to minimise powertrain control module pin count.
Inventor: ZHU GUOMING GEORGE
IPC: F02P5/15
Filed: 2004-07-22
Abstract: A method of multiplexing ionization signals 106-109 from a plurality of cylinders 90-93, consists of calculating an action period (124, fig.10d); combining the ionization signals, whereby information from said ionization signals is spaced apart by at least an action period in duration; and outputting the ionization signals, whereby no overlap of information occurs between the ionization signals. Simply the method multiplexes the ionization signals to reduce the powertrain control module (PCM) 121 pin count. Preferably an inline I.C. engine 1 has five cylinders whereby the total pin count is reduced from the total number of five, to one. Alternatively, a summer 15 may be used instead of a multiplexer to reduce the pin count.

Title: Trading portfolio risk management
Inventor: WILSON BRIAN
IPC: G06Q40/00
Filed: 2004-10-29
Abstract: The application relates to a system for managing risk for a trading portfolio in a trading environment. The system includes means for obtaining data relating to trading elements in the trading portfolio and means for calculating a risk factor based on the data obtained.

Title: Security sensor device having optical axis adjustment capability
Inventor: IWASAWA MASASHI
IPC: G08B13/183
Filed: 2005-01-25
Abstract: There is provided a security sensor device having an optical axis adjusting capability, which device includes a beam projecting unit 1 for projecting sensing waves, to which ID codes for specifying beam projectors 2 are applied, to a beam receiving unit 8 sequentially at predetermined intervals. The beam receiving unit 8 detects the level of light received by each of beam receivers 9 corresponding to or identified by the respective ID codes and transmits the received light levels to the beam projecting unit 1. According to these features, during the optical axis adjustment the levels of light received by the beam receivers 9 can readily be obtained on the side of the beam projecting unit 1, resulting in an accurate adjustment of optical axis between the beam projectors 2 and the beam receivers 9 in a short length of time with a simplified structure. The sensing wave may be a pulse modulated infrared beam.
